If it works for you, I might persist.
Just in case anyone is following along at home, I have got this working again. Recall that the symptom was that some pages would render the profile summary bar alone: just a lone div was returned, no other page content. Working back from here, I looked at the PFSummary delegate that generates that div. PFSummary.responseEnded() takes a WOResponse, and calls appendContentString() on it a bunch of times to add the trailing div. For reasons which are not clear to me, the first call to appendContentString() would sometimes cause the existing content to be dropped, leaving just the appended strings. (Either that, or there's something else going on and it's a coincidence.) So a workaround was to: 1. Save response.contentString(). 2. Replace the calls to response.appendContentString() with append() calls to a StringBuilder instead. 3. On the way out, concatenate the saved contentString and the result of StringBuilder.toString(), and call response.setContent() with that string. This certainly gets ERProfiling working on this project for me, though it's unsatisfying. -- Paul Hoadley https://logicsquad.net/ https://www.linkedin.com/company/logic-squad/
